We report on the microstructure and mechanical properties (elastic modulus) of concentrated depletion and thermal gels of octadecyl-coated silica particles for different values of the strength of interaction--polymer concentration for depletion gels and temperature for thermal gels. The depletion gels are composed of dense clusters and voids, while the thermal gels are devoid of clusters. Shear...

Two novel cyclodextrin derivatives were synthesized that could self-assemble into a supramolecular polymer and gel in different solvent environments. Importantly, the obtained self-assemblies, including vesicles, micro-fibers and gels, could respond to various external stimuli efficiently.

Surfactants based on imidazolium ionic liquids (ILs), including polymerizable surfactant ILs, have been synthesized and used to stabilize polymerizable microemulsions useful for producing polymer nanoparticles, gels, and open-cell porous materials.
